High up Hagg Beck this twin entranced shakehole in black limestone has been on our list for many years after a good report from Harry Long. It was Phil Parker that finally dragged us up there.We have gained a rift at 4 metres depth that bells out underneath and is an old stream sink. Unfortunately the wider part is full of collapse material from the shakehole and progress can only be made for a few metres until stopped by loose flakes. Work continues.
